摘要
Effective enantiomeric separations of 1-benzyl-N-methyltetrahydroisoquinolines were achieved using commercially available Chiralcel OD-H and OJ-H columns. Online LC-CD analysis allowed for the establishment of a correlation between the absolute configuration of the separated enantiomers and their characteristic CD transitions. LC-MS combined with LC-CD analysis permitted chiral purity determinations of O-methylated metabolites of nine phenolic 1-benzyl-N-methyltetrahydroisoquinolines in cell cultures of Corydalis, Macleaya, and Nandina species.
